If you are using a pista pump or super pista pump produced after 1946, this check valve assembly is built in to allow air to flow in only one direction. We've updated this rebuild kit with a classic brass plunger and a new O-ring that replaces the piano wire spring with a stainless steel spring. Check valves generally had to be replaced every 20 to 25 years, but we believe that advances in material technology have pushed it forward to 30 to 35 years.
